Hi,
I have been using various Debian-based distros for a couple of years now.
I retired my Ubuntu 10.04 installation last Xmas, and installed Precise (12.04). My only means of internet access is by mobile broadband.
I have been unable to connect to the internet by any Ubuntu after 10.10.
I quite liked the look of LXLE 12.04.3, but of course was unable to connect again.
After joining this forum, I found that someone had had a similar problem, and copied a few commands which were recommended.
This afternoon, I booted the live DVD of LXLE, set up my mobile broadband in Network Manager as normal, unplugged the dongle and plugged it back in again, and was connected! Opening a terminal window, "dmesg |tail" showed that the dongle had been connected, disconnected, and reconnected again in a different way, thus:

Any suggestions as to how I can achieve a reliable Internet connection?
I am currently using Solusos, and the only other distro which seem to work reliably is Debian itself - I have Wheezy with the Xfce desktop from the magazine disk installed on my laptop.
All the best,
Rojj

Hi Nelz,
Booting with the dongle in place, as normal.
I've noticed that the list of usb modems begins "E220"
Mine is an ?E156?
Will boot a live CD of 10.10 tonight and see if my usb modem is included in a "lsusb"
Regards,
Rojj

Hi Nelz,
I removed the dongle, rebooted, inserted the dongle and set up through Network Manager. No success, although "dmesg |tail" showed that the dongle was removed and re-inserted using ?ehcpi, which was the same as happened on my one successful attempt at getting on line with lxle.
Here is the code:

Hi All,
Further to my post yesterday,
I am currently running a live dvd of Debian 7.
Booted with dongle in.
Mobile broadband set up in Gnome 3 with no problems.
Here are the results of the usual 3 commands:

Hi,
Just to see if I had been doing things in the wrong order, I booted "dongle-out", set up in Network Manager, and then inserted the dongle.
Nothing doing, though the last couple of lines of "dmesg |tail" seem as if it was killed off somehow.
